The shelf life of milk depends on several factors, including the type of milk, how it's stored, and whether it has been opened. Here are some general guidelines:
-
Pasteurized Milk: Typically, pasteurized milk lasts about 1 week beyond the "sell-by" date if properly refrigerated. Once opened, it should ideally be consumed within 5-7 days.
-
UHT (Ultra High Temperature) Milk: UHT milk can last several months unopened at room temperature. Once opened, it should be refrigerated and consumed within 7-10 days.
-
Raw Milk: Raw milk has a shorter shelf life and should generally be consumed within 7 days if refrigerated.
-
Storage Conditions: Milk should be stored in the coldest part of the refrigerator, not in the door, where temperatures can fluctuate more.
-
Signs of Spoilage: Look for changes in smell, taste, texture, or color. If the milk smells sour or has lumps, it's best to discard it, regardless of the date on the packaging.
Always check the "sell-by" or "use-by" dates and trust your senses when determining if milk is still good to consume.
